What happened
SigTuple Technologies of India makes AI100 with Shonit, an automated microscope that scans stained blood smears. A convolutional neural network locates and classifies white cells, red cells and platelets for review by a skilled operator. In a method comparison at four sites, 882 samples from healthy people and patients were read on the device and by manual microscopy. Two examiners at each site evaluated randomly selected, blinded slides. FDA reviewers report that the device's results caught abnormal white-cell findings with 92.7% sensitivity and 95.4% specificity against manual microscopy. They write that the study met the pre-defined acceptance criteria. FDA cleared the device on 19 September 2023. The study measured agreement with manual microscopy and did not measure time saved. An operator still identifies and classifies each cell.

A method comparison study was conducted at four (4) sites comparing the AI100 with Shonit to manual microscopy. A total of 882 samples were collected encompassing healthy subjects and patients with specific disease conditions. Blood samples (K2EDTA) were collected, and one peripheral blood smear (PBS) slide was prepared for each sample (Romanowsky stain). The slides were randomly selected, blinded and evaluated by two examiners at each site. Passing-Bablok Regression analysis was performed for WBC differential and overall agreement, sensitivity and specificity were measured for WBC Distributional and Morphological abnormalities. Overall agreement, sensitivity and specificity were evaluated for RBC and PLT morphology. Calculations of 95% confidence intervals are also provided. The study met the pre-defined acceptance criteria.

AI system
- Workflow
-
Each sample was smeared on a slide and stained with a Romanowsky stain. The device scanned the smear and classified white cells, red cells and platelets on each image.
Follow-up
- Conditions for replication
-
A skilled operator trained on the device reviews the cells and classifies each one. The device is used in a clinical laboratory.
